So (BN) is flawed because it cannot enforce mate on 3x3 now? What kind of
reasoning is that? Falcon cannot do that either. In fact, it cannot even
move on a 3x3 board. Does that mean it is even more fatally flawed?

I think it is a mistake to consider using a different array as creating a
new variant. I usually refer to such things as sub-variants. In the
WinBoard GUI, 10x8 games like Carrera, Bird, Embassy are all played as
'variant capablanca'. If not actually playing Capablanca, the user will
have to provide the opening setup (as FEN).

I guess (BN) and (RN) are so popular because their play is appeling in
practice, and they blend in well with the usual crowd of FIDE pieces.
